China's economic growth is expected to continue into the next decades, accompanied by sustained urbanization and industrialization. The associated increase in demand for land, water resources, and rich foods will deepen the challenge of sustainably feeding the population and balancing agricultural and environmental policies. We combine a hydrologic model with an economic model to project China'...
Many concerns over global change can be linked to the health and well-being of humans. Our welfare is intimately tied to that of our environment, resource base, and common home. Health effects can be traced from many factors, including changes in water resources, forests, agricultural production, atmosphere, and most other domains that will be affected by climate change. However, here we focus ...
INTRODUCTION This study evaluated whether pharmacogenomic information contained in the Food and Drug Administration (FDA)-approved package inserts of sixty-five drugs was present in five drug information resources. METHODS The study searched for biomarkers from the FDA package inserts in 5 drug information sources: American Hospital Formulary Service Drug Information (AHFS), Facts & Compariso...
China's water resources are under increasing pressure from socioeconomic development, diet shifts, and climate change. Agriculture still concentrates most of the national water withdrawal. Moreover, a spatial mismatch in water and arable land availability--with abundant agricultural land and little water resources in the north--increases water scarcity and results in virtual water transfers fro...
Background People suffering from food allergies must study food ingredients prior to consumption. While the Internet facilitates this information acquisition, little is known about consumer experiences. One aim of the BELANA trial (Burdens and Expenses of Living as Adult with Nutrition based Allergy or Intolerance) was to study the use of, and satisfaction with, Internet information sources by ...

The composition, abundance, and relationship to trunk-surface characteristics of the tree-trunk surface arthropod fauna were studied from August, 1984 to January, 1985 in a beech-maple forest in southwestern Ohio. Samples of trunk-surface arthropods were taken monthly from American beech and sugar maple trees. Although resource levels on the two tree species did not differ significantly, arthro...
A Bayesian mixing model and stable isotopes of carbon, nitrogen, and hydrogen were used to evaluate the extent to which six consumers (three fishes, two zooplankton, and a snail) in a naturally productive lake used terrestrial resources, epilimnetic and metalimnetic phytoplankton, benthic algae, and macrophytes. Resource use varied with consumer habitat use and feeding ability, but allochthony ...
irrigated agriculture is an important contributor to the expansion of national food supplies and is expected to play a major role in food security of developing countries. such countries face water crisis for securing the food staples. well designed water resource policies potentially can improve the water allocation and use efficiency as well as the food security objectives. this paper present...
